Each transmission and guidance unit comprises a male element mounted on one of the scroll plates and a facing female element mounted on the facing scroll plate. Each transmission and guidance unit comprises an internal ring mounted for angular displacement in the opening of the female element, the internal ring having therein a slot wherein the male element of the transmission and guidance unit slides. The male of the three transmission and guidance units are supported and guided by respective support elements on a common external guide ring. A liquid injection system comprises a liquid channel which is connected with bleed holes.
